    I have added te screenshots to the article, hope it may the article more informative.
    As for the GastCGI issue, if you are using SELinux, check the following article: https://support.plesk.com/hc/en-us/articles/213361389-Cannot-send-email-using-PHP-mail-function-Unable-to-rename-usr-local-psa-handlers-spool-messageXXX-file-Permission-denied

    Hi @William Dugger,

    Maybe the issue is related to the PHP script itself?

    In order to check it, perform the next actions:

    1. Create a file under the domain home directory with the following content:

    mail('johndoe@example.com','hello','test mail function');

    2. Make sure that PHP support is enabled for the domain at the "Plesk > Domains > example.com > PHP Settings" page

    3. Try to open the PHP script via a browser:


    If the issue still occurs without any info in logs, it is better to create a request to Plesk Support for further issue investigation
